Most slaty cleavage is also axial-plane cleavage. Synonym of: flow cleavage. WebIn low-grade metamorphic rock, S1 is typically a slaty cleavage and S2 is a crenulation cleavage. In mylonite, commonly the schisosity (S) is interleaved with shear bands (C) to define a composite and more or less synchronous S–C fabric.

Slate Rock Definition, Composition, and Uses - ThoughtCo

WebSlate A very fine-grained metamorphic rock (usually developed from clay -rich sediments) exhibiting perfect planar layering and perfection of splitting into layers (slaty cleavage) is slate. Such rocks are normally rich in micas and chlorites. Slate is a fine-grained metamorphic rock that shows no obvious compositional layering, but can easily be split into thin slabs and plates. It is usually formed by low-grade regional metamorphism of mudrock. This mild degree of metamorphism produces a rock in which the individual mineral crystals remain microscopic in size, producing a characteristic slaty cleavage in which fresh cle…
